Hello! I know it's not one question, but hints on how to start each problem? I'd greatly appreciate it

Prepare a water budget for the year 2009 for the basin and the unconfined sedimentary aquifer that constitutes the basin illustrated below (map view). 100 km 850m 800m 80 km 30 km 750m D 1 oom ti 100 km Stream 20 km Hydraulic head contour The basin is surrounded by a topographic divide that coincides with the water table divide. The basin has a surface area of ~8500 km2. The unconfined aquifer has a hydraulic conductivity of 20 m/day, a thickness of 6 m and a Specific Yield of 0.12. The climate is such that evapotranspiration is about 80% of precipitation. The basin is residential with approximately 5000 homes obtaining water from domestic wells. Precipitation Stations Annual Precipitation for 2009 was the same as the average annual precipitation for the past century A 830 mm B 620 mm Water Level in meters Measured at the precipitation stations Contoured Water Levels are July 1, 2009 Location Jan 1, 2009 Dec 31, 2009 C D 850.8 m 800.3 m 751.1 m 849.3 m 798.8 m 749.6 m E Stream Gage X 2009 Average Annual Discharge 26 meters/sec 1) Write a water budget equation for the basin (think the following small questions first). What is the precipitation (P) into the basin in 2009 (m3/yr)? What is the evaporation (E) out of the basin in 2009 (m3/yr)? What is the stream flow (SF) out of the basin in 2009 (m3/yr)? Is the groundwater flowing into the stream or is the water in the stream flowing into the groundwater? What is the amount of water flow for this term (GS) in 2009 (m3/yr)? 2) Write a water budget equation for the aquifer (think the following small questions first): What is the amount of groundwater flow out the aquifer via the stream (GS) in 2009 (m3/yr)? What is the groundwater flow (GW) out of the aquifer underneath the stream in 2009 (m3/yr)? What is the change of storage (S) in groundwater in 2009 (m3/yr)? What is the amount of water (H) that the 5000 homes pumped from the aquifer in 2009 (m3/yr)?
