Hydrology

Water is a vital resource for human development; its natural mode of occurrence is governed by climatic, geomorphic and geologic characteristics of the land surface. Water resources is a major requirement and driver of socio-economic development. Economic sectors that water caters to include domestic, agriculture and fisheries, industry, recreation, municipality, including waste/effluent disposal, and water transportation. It also plays a prominent role in power and energy generation (Oyebande.,

Water Resources of Botswana Rebecca Pitcock The purpose of this report to address and discuss the water resources of Botswana, in both qualitative and quantitative analysis. Through research of government websites as well as scholarly journal articles, a better understanding of Botswana and its water resources will result. This report will address surface water such as rivers, streams and lakes, as well as the issues of said resources. There will also be an analysis of groundwater reservoirs

Long Branch, a tributary to Four Mile Run, drains heavily urbanized southeastern part of Arlington County. The area is partially protected by a short levee on the left bank near its confluence with Four Mile Run. Streams Tech personnel conducted a limited detailed study to develop a HEC-RAS model, establish water surface elevations, delineate floodplain boundaries and assist the Arlington County in evaluating floodplain management scenarios. GIS data were obtained from Arlington County to support

Introduction Rivers and streams are supplied with water that runs of the landscape surface and flows into the them, this area of land where this occurs is called a catchment (Holden, 2012).There are many issues that are related to urban hydrology and catchments, however, the most problematic and frequent one is flooding. Flooding occurs when high amounts of rainfall fall in the urban area and accumulates on the surfaces, due to the high development in urban areas. This is because most surfaces in

China’s ability to cope with its limited fresh water resources may be the greatest determining factor in the nation’s future prosperity as well as the wellbeing of the Chinese people. Though not entirely without freshwater reserves, the mere size of the nation’s population dictates that China fails to be a water abundant country. Recent decades’ rapid development, inefficient water usage, and pollution have given way to a severe and growing water crisis. As a key component of the government’s

constant water movement above, on, beneath the earth’s surface by the means of evaporation and transpiration, condensation, precipitation, and runoff /infiltration/ recharge. Hydrologic cycle has neither beginning nor an end. Basic ground-water hydrology vater-supply paper 2220. 2. Define evaporation. Evaporation is the first water cycle step. However, evaporation describes as a water movement from the surface of the oceans into the atmosphere, which represent 85% of the water vapor/steam and the

function of the substances that contact with either in-flowing or still water and how long been there with their exposure to the sunlight or wind. The constituents from varied sources that are entering or leaving (river/lake) can be a function of the hydrology and topography system. Water from sources such as direct/indirect precipitation, surface runoff from snowmelt, or storm water from exposed rock or packed soil, or groundwater inflow from the aquifer will react with the soil or bed/sedimentary rock

Other Factors Contributing to the Flood The Arun and Sunkosi sub-catchments of the upper catchment area contribute to the intensity of floods, with the former possessing highest surface runoff potential (Wakode et al., 2013). As the Kosi River exits at the base of the mountain, the ability to transport sediment is dampened, leading to deposition of sediment and aggradation (Kale, 2008). High silt content in the river was due to soil erosion and landslides and the presence of narrow gorges (Wakode

Project Description The landscape features present in an area greatly influence the areas hydrologic organization. Hydrology is the subdivision of the earth sciences, which deals with the storage and movement of water around the earth, the physical and chemical feedback of water among the environment, and the relation of water to living organisms (Hendricks 1962). Changes in the landscape alter the area’s natural hydrologic flow. These changes may alter the stability of river channels, the heights
