Andhra Pradesh Groundwater Assessment

Andhra Pradesh water this week

What this is: The State at a glance: every mandal's groundwater on one map, with the places that need attention first.
What it says now: The State's 1,746 wells averaged 11.4 m below ground on 9 Sep, 3.2 m deeper than a year ago. 402 mandals read groundwater stress.
What to do with it: Start here; open a district or mandal for its record, or This Week for what changed.

Measured & Modelled Values

These are not competing sensor readings. APWRIMS is observed depth history; the β value is this app's calculated mandal groundwater level for the current target period.

Backed by its recordForecasts made in September after near-normal rain beat assuming no change by 12% (2.06 m against 2.35 m average error over 5 years). They expected less water than came, by about 0.7 m. Rain here over the three months to the forecast: +2% against normal.

Only the three-month horizon is released, on rolling-origin validation. Both ranges are model P10–P90 quantile ranges, not guaranteed confidence intervals.
