Project Experience

Washington D.C. Extreme Precipitation Analysis

Client: Climate Decision Ltd

Sub-daily rainfall extreme events are recognised as one of the most critical to infrastructure planning in urban environments. With advancements in data quality and length of records and methods of analysis climate change can now be considered in these analyses. CLIMsystems has been a leader in the field of climate risk assessment applying innovative methodologies that deliver practical outputs based on the application of the latest Coupled Model Intercomparison Project Series 5 data (CMIP5). Extreme precipitation return periods and exploration of changes of intensity of rainfall with different temporal resolutions shows that the differences are considerable and should be considered in designs.


Miami, Florida, USA. Ocean Outfall Legislation Project

Client: Miami Dade Water and Sewage Board

CLIMsystems performed a comprehensive risk assessment for sea level rise and extreme sea level rise using well defined parameters and climate sensitivities. The data was used to drive a Mike 21 coastal hurricane surge model. Wind and sea level pressure GCM data was processed. Spatial IDF using an ensemble of daily GCM patterns for assessment of the capacity required for the new sewerage infrastructure and CLIMsystems reviewed site specific IDF work carried out using SimCLIM software. CLIMsystems presented at meetings and wrote Technical Memorandums for each variable modelled. We cross validated all work with other studies.

SW Tobago Climate Change and Coastal Vulnerability/Adaptation

Client: InterAmerican Development Bank

For SW Tobago, the near shore islands and coastal fringe is the nexus where the impacts of climate change and social and economic wellbeing intersect most vividly. CLIMsystems modelled the impact of sea level rise and changes in temperature and precipitation. We applied the latest CMIP5 GCM data. We included not only sea level rise information but also wind and sea level pressure data so that extreme events in sea level changes could be modeled to the year 2100 with various time slices (baseline of 1995, 2030 and2050). Other marine variables: sea surface temperature and pH value were modelled.


IDF Curves Singapore: Historical and Climate Change Influenced

Client: Singapore PUB

CLIMsystems assisted Singapore in developing IDF curves for the central area of Singapore. The results fit with current IDF modeling but with climate change important trends emerged. Using daily general circulation model patterns and through the assessment of a range of extreme event analysis tools CLIMsystems provided an envelope of potential scenarios and probability analysis. CLIMsystems derived the rainfall intensity time series of different durations from historical hourly data time series. The durations included: 1, 2, 3, 6, 12, 24, 48, 72, 120 and 168 hours series. Six distribution functions were tested,: Generalized Logistic, GEV, Generalized Normal, Pearson Type III (PT3), Generalized Pareto and Gumbel.


Bengaluru City, Water and Waste Water Master Plan, India

Client: Bengaluru Water Supply and Sewerage Board

CLIMsystems was contracted to provide overview climate risk assessments of the water supply areas: Cauvery Basin and also the Arkavathy Basin and Bengaluru City areas using the latest CMIP 5 GCM and RCM data. We also engaged closely with the client on assessing wider impacts of extreme temperatures and changes in seasonality and variability of droughts and extreme rainfall events and their potential impact on infrastructure.


Financing Low-Carbon, Carbon-Resilient Urban Infrastructure in Asia and Pacific

Client: Asian Development Bank

CLIMsystems has been tasked with providing the climate risk support for the assessment of over 200 cities across the Asian Development Bank’s member countries with population greater than 750,000. Greater depth of analysis is being carried out for six model cities and two of these six will be examined in detail. CLIMsystems has developed a distinctive City Risk Profiling tool for rapidly assessing climate risk and other socio economic aspects as well as a integrating analysis through the new CLIMsystems Decision Support tool built on system dynamics principles. The integration of carbon footprint data for key city infrastructure and assessment of climate risks to that infrastructure and exploring financial mechanism for implementing climate resilient and low carbon development are the key drivers for this project. CLIMsystems is partnered with Ramboll Environ and has a close working relationship with the ADB.


Adapting to Climate Change in China Phase II (ACCC II)

Client: INTASAVE-CARIBSAVE Group UK

The Adaptation to Climate Change in China Phase II (ACCC II) is a risk-based adaptation planning process project – from engagement, to research to practical support of adaptation policy and option formulation. CLIMsystems has developed through consultation at the Provincial level a new system dynamics modelling system for integration of climate change information and a wide range of sectoral data at the provincial level to feed five year plans for adaptation and mitigation. Six pilot provinces are well underway and the program will be rolled out nationally in 2016/17.


Adaption Atlas

Client: re:focus and Clinton Global Initiative (CGI)

In 2014 CLIMsystems was approached by re: focus and Blue Raster to develop seas level rise and extreme rainfall data layers for the world for inclusion in a Clinton Global Initiative sponsored on line Adaptation Atlas. CLIMsystems also developed a very useful city comparison tool for exploring communalities across 1600 cities for current and future climates. The Atlas includes examples of successful adaptation interventions and was one of five project selected at the 2015 Clinton Global Initiative meeting in Denver, Colorado for further development.


Qatar FIFA World Cup 2022

Client: FIFA Qatar Supreme Committee

Once awarded the FIFA World Cup the design of new infrastructure became paramount. ARUP in collaboration with CH2MHILL were charged with designing the new infrastructure and managing the build. CLIMsystems was hired to provide wind and temperature and heat index modelling and new weather file for 2022. With reports and oral presentations to the FIFA Supreme Committee and others a decision was later made to move the FIFA World Cup to cooler winter months.


Climate-Resilient Coastal Protection and Management Project, India

Client: Asian Development Bank

The coast of Maharashtra and Karnataka States in western India are the focus of this project striving to upskill Indian institutions in coastal risk assessments and climate change modelling and implementation of appropriate interventions to reduce the impacts of sea level rise and storm surges. CLIMsystems is playing the role of coastal specialist with an emphasis on sea level rise and storm surge modelling and providing support to Indian institutions completing GCM downscaling. CLIMsystems will also process data for on-line availability.


Tajikistan- Building Capacity for Climate Resilience
