The way how the hydrology is established to agriculture will differ according to the country as it involves natural environments. Its application to agriculture is established in irrigation, drainage, and soil and water conservation. The hydrological application in general will be presented briefly in this paper.

 

Application of hydrology to irrigation

            Hydrology in irrigation is constrained to the analysis of irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers while the temporal domain spans from seconds to centuries. It is applied to the estimation of effective rainfall, evapotranspiration, streamflow, and inflow into a reservoir. Irrigation planning is usually made against such a droughty year as occurring several times in several-ten years so that irrigation water can meet the requirements for most years. This estimate probably includes the utilization of rainfall detained in dual-purpose canals.

 

Application of hydrology to drainage

            The primary hydrologic unit considered in fluvial geomorphology is the basin. It is a source for water and sediment that moves from a higher elevation through the river system to lower elevations as they reshape the channel forms. Historical concerns focused on increased flows during rains and associated flooding. However, decreased flows during dry periods are now seen to cause receiving water problems. The historical approach to urban drainage has been devastating to the environment and recharge of groundwaters as it has a lot of factors affecting the making of the drainage design.

 

Applicaton of hydrology to soil and water conservation

            Soil and water conservation is an integral part of Watershed Management. Watershed Management was reviewed formerly to be nearly synonymous with soil and water conservation but still, it has to comprise a variety of further activities that attempt to improve the living conditions of the people living within the respective watershed. Soil and water conservation are those activities at the local level which maintain or enhance the productive capacity of the land including soil, water, and vegetation in areas prone to degradation through

  • prevention or reduction of soil erosion, compaction, salinity;

  • conservation or drainage of water and

  • maintenance or improvement of soil fertility (WOCAT 2007).v
