Rainfall intensity-duration-frequency relationship and nomographs are required for design of soil and water conservation structures. Rainfall IDF relation depends on the physical characteristics of rainfall occurring in a particular place. The rainfall IDF relationship can be expressed as, I= (KTa) / (t+b)d in which, I is maximum rainfall intensity (cm/h), T is return period (years), t is duration (h) and K, a, b and d are location specific constants. These specific constants in above relationship vary location to location and calculated by evaluating the rainfall IDF relationship. The study was undertaken to develop the rainfall IDF relationship and nomograph for Arni tehsil of Yeotmal district of Vidharbha region. The required automatic rainguage charts were collected from Arni station of hydrology project. These rainfall charts were analyzed for maximum annual rainfall intensity of selected duration's viz., 0.08, 0.16, 0.25, 0.5, 1, 2, 3, 6, 12 and 24 hours. The plotting positions were obtained by using the 'computed method' for development of frequency lines. Value of constants a and b were determined by using graphical method and the values of K and d were determined by using least square method. The values of constants K, a, b and d were found to be 3.148, 0.2074, 0.12 and 0.5574 for Arni station of Yeotmal district. The nomograph was developed for the IDF relationship for the same station.Keywords

The study was carried out on the preparation of contour map for Makhamalabad site and to determine the morphological characteristics of Makhamalabad mini watershed. Topographic surveying and planning was done for Makhmalabad farm. The watershed selected for the study is located off Peth road at Makhmalabad village of Nashik district. The area of watershed undertaken to study is 4.2 ha. Survey was carried out with grid spacing of 20 m. Contour interval was taken of 1 m. From the study of watershed characteristics it was seen that the watershed has fan shape with small catchment area of 4.2 ha, with stream order 1. The drainage density was 0.051 km per sq km. which was relatively very less. So, runoff from catchment was also less. Time of concentration was 3.44 min. It is seen that the watershed has stream order 1. There were more streams per unit area. The drainage density was 0.051 km/km2. Thus, the average length of overland flow was more. The area of watershed was less so also the slope and length of stream. This has resulted in higher time of concentration, which was 3.44 min. The length-width ratio was also higher.Keywords
