People often say that groundwater flows from topographic high to topographic adjacent low. Using hydraulic head and other concepts of hydrogeology, how would you explain this?
A dam is to be built across a valley to form a reservoir, and the areas in the corresponding Table Q2 (a) enclosed by contour loops were taken from a plan of the area concerned. Using the Prismoidal formula, compute the volume of water impounded when the water level reaches 200 m if the 160 m level represents the reservoir's level floor.
3. The boundary of the water surface of a reservoir is shown by irregular outline KLMNOPQR. Soundings were taken on parallel ranges QK, PL, and OM for the purpose of determining the volume of water in the reservoir. The horizontal distances (m) which were measured for locating the ranges and the soundings, and also the depth (m) which were measured where soundings were taken are shown. Calculate the following: a. Areas (sq.m.) of the cross-sections of ranges QK, PL, and OM. Assume that the cross-sectional areas of ranges R and N are negligible or nearly zero. b. Volume (cu.m.) of water between ranges. c. Total volume (cu.m.) of water contained in the reservoir.

help asap, 2 decimal places thank you!In the accompanying plot (shown next page), the boundary of the water surface of the lake is represented by the irregular outline ABCDEFGH. Soundings were taken on parallel ranges BH, CG, and DF. The values indicated in the plot, all of which represent lengths in meters, show the horizontal distances which were measured for locating the ranges and the soundings, and the depths which were measured where soundings were taken. Note: Distances from the cross-sections from A-B, B-C, C-D, D-E are 10, 14, 15, 20 meters respectively. a.
