It is strongly recommended to provide mechanism for safe disposal of excess runoff. Improvements in soil conditions and soil-water regime can be accomplished by runoff management techniques. Various field management techniques suitable for dry areas are described below: 1. Indigenous Techniques: a. Farm Bunding: In this technique a bund is constructed around the field using local earth material. Primarily, this [...]
After reading this article you will learn about the measurement of soil in the runoff with the help of small plots and watersheds. Small Plots: Runoff and soil loss from small rectangular plots of one soil type and one slope gradient can be collected in a tank placed at the bottom of the plot. Sometimes dividers are used to sample [...]
After reading this article you will learn about the hydrologic cycle and its components. Runoff, a potential carrier of nutrients and sediment to streams and lakes is best described in the science of hydrology. Two basic physical principles governing the amount and distribution of water on the earth are those of mass conservation and energy conservation. These principles, along with [...]
