25-Newer techniques of watershed measurements

Abstract

To keep pace with the advancement of hydrologic investigations and research with more and more computer applications in water resources engineering leading to formulation of a large number of watershed models specially in developed countries, the need for intensive instrumentation of watershed, longterm monitoring at shorter time intervals, automation of monitoring techniques, electronic recording, storage and retrieval of data through computer interfaces and development of reliable equipments is increasing more than ever. Long term measurements of watershed parameters with sustained accuracy is the single most factor having all round impact on the efficient management of water resources and its development of the watersheds. Therefore, water resources managers are always on the look out for better materials and methods for watershed measurements. In this chapter the authors review some of the recent advancements in equipment for watershed measurement related to hydrology and allied subjects.
