Chapter One: Introduction to Land Drainage What is Drainage? • Definition: Drainage, in the context of land management, refers to the removal of excess water from the soil surface or subsurface. It encompasses both natural and artificial processes that facilitate the flow of water away from areas where it is not desired. • Beyond Excess Water: It's not just about removing water but also about controlling its level, movement, and quality to achieve specific land use objectives. • Importance of Water Balance: Drainage is closely linked to the concept of the water balance. The water balance equation (Precipitation = Evapotranspiration + Runoff + Infiltration + Change in Soil Moisture Storage) highlights that if precipitation exceeds the other components, especially infiltration and evapotranspiration, drainage will be needed to manage excess water. • Key Processes in Drainage: o Infiltration: Water entering the soil. o Percolation: Downward movement of water within the soil. o Surface Runoff: Water flowing over the land surface. o Subsurface Flow (Lateral Flow): Water moving horizontally below the surface. o Evapotranspiration: Water loss from the soil surface and plants. 1. 2.

perennial crops like sugarcane ,cutton,etc require water throughout major parts of the year but the rain fall may fulfill the water requirement in rain season only. So for remaining part of the year irrigation becomes necessary. Development of agriculture in desert area -in desert area where RF is very scant , irrigation is required for the development of agriculture. The following are some of major advantages of irrigation: 1. Increase in crop yield: 2. Protection from famine: 3. Cultivation of superior crops 4. Elimination of mixed cropping 5. Economic development 6. Hydro power generation 7. Domestic and industrial water supply Irrigation water sources may come from, Surfaces water sources Ground water sources Water harvesting/Rainwater sources Desalinated Water sources Recycled Water Water present on the surface of the earth in the form of oceans, rivers, lakes, ponds and streams is called surface water. Surface water accumulates mainly by direct runoff from precipitation i.e., rain or snow melting. The amount of available surface water depends largely upon rainfall. Examples of Surface water sources includes: Lakes Rivers Streams Drainage ditches Private ponds Dug well with or without straining walls wells Cavity Bore Radial collector wells Infiltration galleries , Tube wells& bore wells, Groundwater that flows naturally from the ground is called a spring Deep well Shallow wellBecause water is essential for plant growth and it serves the following functions.

Fertilizers are applied to the soil to increase the available supply of plant nutrients (principally nitrogen, phosphorous, and potassium) and thus promote greater yields or better crop quality. Fertilizers can be applied to the soil in several forms: Barnyard manure Granular/coarse and pelleted/capsule fertilizers of various formula Fertilizers in liquid and gaseous form Special equipment is, therefore, required for the handling of these types of fertilizers, which are applied to the soil and crop in various ways at different stages of culture. Fertilizers can be organic and inorganic fertilizers. Organic fertilizers include farmyard manures, which are applied in large quantities. Inorganic or commercial fertilizers include urea, DAP, supper phosphates, which are applied in smaller predetermined quantities relative to the organic ones. The fertilizer equipment needed will, therefore, be selected depending on the type of fertilizer and the form of application. All types of fertilizer equipment will have; Storage unit Metering mechanism Carrying frame attached with Planters Dry, granular fertilizers have for many years been the most common types of fertilizers used by farmers. Their applicators can be designed as attachments with planters so as to permit dual operations in connection. ]]>

GIS AND REMOTE SENSINGN In many irrigation projects, crop yields are reduced due to water logging and salinization of the land. In some cases, there is total loss of production and therefore the land is abandoned. Water logging may also cause human health problems, particularly malaria, because of ponded water. Two important causes of water logging and salinization are: Part of the water that infiltrates into the soil will be stored in the soil pores and will be used by the crop; another part of the water will be lost as deep percolation. When the percolating water reaches that part of the soil which is saturated with water, it will cause the water table to rise . If the water table reaches the root zone, the plants may suffer. The soil has become waterlogged. Drainage is needed to remove the excess water and stop the rise of the water table. ]]>
