Spatial Dynamic Optimization Of Water Use And Management Behavior

According to the International Water Management Institute environmental research organisation global water stress is increasing, and a third of all people face some sort of water scarcity. Where demand exceeds supply and no effective management operates, there will be conflicts between the various players involved.

The upper basin states (including Colorado) were allocated a much greater percentage of the water than the lower basin states, while the upper basin states were developing at a much slower rate than those in the lower basin, notably California. Nevada (as of 1997) anticipated being unable to rely just on this water by 2015, while in 1997 California was already exceeding its originally allocated supply by diverting unused water from the upper basin states (Arizona.edu, 1997). It goes without saying that this legislation from the early twentieth century is not going to be sufficient in coming years as the development of these regions has progressed at a much faster rate than originally anticipated, and it is the responsibility of state and federal governments, water management companies, as well as appeals from farmers and non-farming residents alike to come to an agreement on how to apportion water and how to implement secondary hydration plans due to the rapidly declining resource that the once-magnificent Colorado River was able to supply us

One of the largest geographic physical structures in the United States is the Colorado River. Human activity and its interaction with this great river have an interesting history. The resources provided by the river have been used by humans, and caused conflict for human populations as well. One of these conflicts is water distribution, and the effects drought conditions have played in this distribution throughout the southwestern region. Major cities such as Las Vegas, Los Angeles, San Diego, and other communities in the southwest depend on the river. It provides water for over 20 million people, irrigation for 2 million acres of land, four thousand megawatts of hydroelectric energy, and over twenty million annual visitors for

With the Colorado River supplying 43% of all agricultural water consumption and 41% of all Municipal and Industrial water supply in the basin, losing access to this resource entirely for one year would cost $1.434 trillion in combined state GDP [2]. Just a ten percent decline in water availability will reduce combined basin states GDP by $143.4 billion, reduce employment in the area by 1.6 million job-years, and reduce labor income by 87.1billion dollars per year [2]. In addition to the shrinking economic production, the cost of living in the area would also start to increase. The water in the Colorado River provides inexpensive energy for the parts of the lower basin states, the cost of the power has doubled from the initial contracts, and if water levels fall to 1000', the costs could quintuple for customers that are bound to purchase the hydroelectric power until 2067 [8]. While the internal economy of the basin would suffer, the effects would also ripple into the rest of the country. The agricultural Imperial Valley in California, for example, provides two-thirds of the country's vegetables in the winter [9]. Without proper irrigation and water supply, production rates

The Central Valley Project (CVP) is a Federal water project set up and run by the US Bureau of Reclamation to provide water for the Central Valley in California. Through twenty dams and reservoirs the CVP facilitates the collection and delivery of water for irrigation, municipal, and industrial use, as well as producing hydropower, providing flood control and recreational facilities on their reservoirs. The CVP provide a good example of how cost allocation works within a vast organization. I will use this organization to describe the method used by the CVP to allocate cost and whether I agree or disagree with their methods. I will also be identifying situations where common costs are allocated. I will explain the impact of allocating

Yet, humans have limited control on natural events, so this only reinforces the importance of managing water wisely. Recently California’s government has begun to focus more on sustaining and restoring the water supply. Dale Kasler (2016) articulates in his article some of the steps they have decided to make to solve this serious issue. The government has made the following investments: “$415 million for watershed restoration and other environmental aid for Lake Tahoe; up to $335 million for two proposed reservoirs in California, including the Sites reservoir north of Sacramento; $880 million for flood-control projects on the American and Sacramento rivers in Sacramento; and $780 million for flood-control projects in West Sacramento” (para. 10). This could be the first step to restoring the water to California. But these

Arizona has an incredibly large dependence on the Colorado River and groundwater. In fact, 39% of all water usage in Arizona is comprised of Colorado River water. Any dependence of that scale on any resource that originates in another area is always a major risk, as any major disaster or drastic change to the source of the river can cripple the state’s water supply. Furthermore, while Arizona does house the majority of the Lower Basin of the Colorado, the Colorado’s Upper Basin is shared between 4 other states, all with their own water needs and all with a susceptibility to drought. On the other hand, another 40% of all water Arizona uses is from groundwater sources. However, the Colorado River and these groundwater sources in the Colorado River basins have lost over 65 cubic kilometers of water over the last 9 years, with nearly 2/3 of it from groundwater loss due to over-pumping. This is because

Texas, with its abundances of natural resources, is facing a new demon, one that doesn’t even seem possible, a shortage of water. Water, without it nothing can survive. Texas is the second largest state for landmass in the nation and ninth for water square miles. Within the borders of Texas are more than 100 lakes, 14 major rivers, and 23 aquifers, so why has water become such an important issue for the state? Politicians and conservationists all agree that without a new working water plan, the state could be facing one of the most damaging environmental disasters they have ever seen. The issues that shape the states positions are population growth, current drought conditions, and who actually owns the water.

As Texas continues to increase in urbanization, the amount of water needed for municipal and industrial uses will increase significantly. More than half the water in Texas comes from underground. Aquifers in some areas of the state are being consumed faster than they can be filled again. Having a sustainable and efficient groundwater management policy is important to ensure that the future water demands will be satisfied.

The city of Fresno has a new water infrastructure program which brings opportunity to transport mountain water down here, so that our groundwater supply can rest, recharge, and be restored. Furthermore, the City of Fresno Water Conservation Program has been encouraging activities that lower water demand in the community to help Fresno meet the many challenges of water supply management. Another measure is that the State Water Resources Control Board has issued a new statewide water conservation policy that executes a minimum level of restrictions and stronger fines. Fresno has also moved to the Stage 2 water shortage contingency plan approved by City Council which regulates water use; it declares to limit summer outdoor irrigation to two days per week, to not water every Monday, Thursday, or Friday during summer, to limit winter outdoor irrigation to one day per week, and not to water every Monday to Friday during winter (as cited in City of Fresno Website,

Arizonans see California’s drought and water restrictions plastered all over the television and newspapers. Many Arizonans remain concerned about the well-being of Californians, while some may mistakenly think that it is not Arizona’s problem. I was one of those people, and while investigated the idea, discover how Arizona is in a bad situation because of it. What I, along with others, did not understand is the years of planning, legislation, and engineering that took place to get water to Arizona and the rest of the Southwest. The Southwest is an arid environment that relies on one river, the Colorado River, to deliver water to seven different

This paper discovers the water budget for Berkeley, California in comparison to Terre Haute, Indiana. The two cities precipitation differs throughout the twelve month calendar year where many of the heavy precipitation months are totally opposite. Berkeley California’s winters, where the majority of rain occurs and Terre Haute, Indiana where the rainfall is observed as consistently disseminated throughout the year evenly. This paper will also magnify geographic position, climate and elevation in contrast of the two cities that reflects the water budget outlined in Project 1: Water Balance defined in
