RMR Groundwater Correction Calculator

Replace independently established groundwater component in same-edition RMR, avoid double subtracting water effect; no rating table or infiltration classification invented. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.

Description

A groundwater component already included in an RMR total must be replaced rather than subtracted twice.

A groundwater component already included in an RMR total must be replaced rather than subtracted twice.^[1]

This reconciliation uses independently assigned same-edition values.

When to use RMR Groundwater Correction Calculator

Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.

How to use RMR Groundwater Correction Calculator and understand its results

Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
Enter callerRmrIncludingOriginalGroundwater, callerOriginalGroundwaterRating, callerIndependentlyReassessedGroundwaterRating, using the field meanings and rules below, then run the tool.
Read groundwaterReconciledRmr. Inspect nested result fields where present, and review unknown records separately from known matches.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
callerRmrIncludingOriginalGroundwater	Caller rmr including original groundwater	list of number	Required
callerOriginalGroundwaterRating	Caller original groundwater rating	list of number	Required
callerIndependentlyReassessedGroundwaterRating	Caller independently reassessed groundwater rating	list of number	Required

Use aligned safe-integer original totals, original groundwater ratings and reassessed groundwater ratings in 0..100. Return total−oldWater+newWater and require the corrected result remain a safe integer in 0..100.

corrected_i=total_i−oldGroundwater_i+newGroundwater_i

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
groundwaterReconciledRmr	Groundwater reconciled rmr	list of number

Limitations and assumptions

Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.

Alternative or Complementary methods

For a related step, use RMR Rating Calculator: An already assigned RMR component ledger can include unknown ratings. For a complementary comparison, use GSI From RMR Calculator: An empirical RMR-to-GSI relation has an edition and applicability branch.
