Side-by-side comparison of design principles, erosion performance, regulatory acceptance, and cost implications. One-page reference for closure plan introductions.

Excel tool for waste rock dump batter geometry — height, run-out, berm widths, and overall slope angles. Output table formatted for closure plans.

Interactive sizing tool — catchment area, runoff coefficient, design event, and basin volume. Includes WA and QLD regulatory compliance checks.

Decision-support guide for gypsum application rates on rehabilitated mine landforms — covers subsoil/spoil stability vs topsoil vegetation use cases, ESP-banded rate tables, five field tests, and a four-tier investigation framework. Methodology rooted in Oster & Jayawardane (1998), Bennett et al. (2022), Spain et al. (2023) and Emmerton & Doyle (2016).

Field assessment guide for erosion risk on rehabilitated landforms — slope, material, cover, and rainfall inputs. Outputs risk classification and inspection frequency.

Excel companion to Field Guide FG-001 — three calculation tiers, 18 Australian material defaults, 8 gypsum-product grades, and a Lab Data Processor with top-5 lab presets. Methodology: Oster & Jayawardane (1998) modified by Bennett et al. (2022); rev 2.8.

How WA, QLD, NSW, ICMM, and World Bank define closure lifecycle stages — OoM, PFS, FS gates, care and maintenance, and relinquishment pathways.
