Modelling irrigation in an ecosystem services framework: A GIS module for the Land Utilisation & Capability Indicator

Stuart Easton

Supervisors: Bethanna Jackson, Mairéad de Róiste

There is a need for spatially explicit modelling of irrigation so that inefficiencies in water use can be determined and targeted for management or mitigation at sub-field scales. A complimentary need exists for irrigation modelling within ecosystem decision support tools so that nutrient and water movements can be accurately quantified. Preliminary outputs from a spatially explicit irrigation simulation model are presented. The model aims to add irrigation flows to the hydrology component of the Land Utilisation and Capability Indicator (LUCI) ecosystem service modelling framework and produce standalone outputs that can inform management decisions. 

Waiting and weighting: Public transport model sensitivity to waiting time and schedule deviation

Richard Law

Supervisors: Mairéad de Róiste, Toby Daglish, Yigit Saglam

Models of public transportation systems can take a variety of forms, but are typically based on the schedule and adopt assumptions about passenger waiting strategies that together lead to a representation that may not accurately  reflect the operation of the real transit system, such as delays and missed connections. Using the complete record of Greater Wellington Regional Council's real-time information (RTI) system, I develop more realistic models of Wellington's public transportation system, and quantify the error associated with travel time estimates and the measurement of spatial accessibility made from models that lack this additional information.
