This paper discusses planning for exceedance as an approach to flood risk management, against the backdrop of a fiscally-constrained economy and pressure on land use in flood risk areas.
Working in partnership with Iwi, the community and key agencies in the region, Nelson City Council has embarked on a four year restoration project for the Maitai River, called Project Maitai/Mahitahi.
Modern asset management systems and Tools are about reducing the friction between the data and users so that asset owners and managers can focus on improved solutions.
In this paper these approaches are benchmarked against each other using a case study. The results show that in some cases there are alternative approaches to the detailed hydrological and hydraulic modelling approach that result in the same end point conclusions being able to be reached (confidence in results).
The paper will explore the refined WAR approach, and an example of the outputs that can be used by infrastructure providers to deliver prioritised catchment-wide network maintenance.
The project involves upgrading an existing 5km stretch of SH20A north of the Airport to motorway standards, constructing a grade-separated intersection at Kirkbride Road by trenching the motorway, and enabling alternative modes of transport via shared paths and cycle ways.
This paper explores some of the tools and processes that have been established using examples of where projects have benefitted from their implementation.
The concept of whakapapa binds Māori to the mountains, land, forests, and waters - all things have mauri, all things have the same origin. Accordingly, the interaction between the environment and people is what determines the welfare of both.
This paper describes the development of a stormwater-specific Mauri Model assessment tool which was trialed on a number of stormwater infrastructure projects. The output from the tool and feedback from Stormwater Department project engineers and Auckland mana whenua are also discussed.
This paper will present an overview and outcome of five (5) major Watershed Management Programs in the Los Angeles area.
This paper endeavors to show how this bottom up approach incorporates community beliefs, focuses on the real problems, creates a multidisciplinary environment, and best utilises community resources for the planning process to meet the challenges of the catchment in hopes of restoring this once vibrant stream.
This paper explores the LDRP from the programme management perspective of identifying information needs, developing stormwater quake damage projects, the process of prioritising and re-prioritising, creating a programme team who are set up for success, and delivering a programme worth hundreds of millions of dollars within a politically driven environment.
This paper will discuss how hydraulic models can be used to develop an Estimated Annual Damage (EAD) value which can be used to compare different flood management strategies, allowing Officers to make economically efficient decisions while maximizing the protection of their communities.
Positioned next to Maungatapere Township in Northland, the residential subdivision Te Mara Estate has been developed with construction undertaken through the 2015/16 summer.
This paper will focus on the risk based assessment and business case development that formed the recommendation to the ECI group. It will include discussion on the quantitative risk assessment including the flood damage assessment, and the economic and qualitative viewpoints encountered along the way.
This paper presents two different project examples where hydraulic, ecological, landscape and other multidisciplinary design elements have been successfully balanced, and identifies the key project features that can be applied in other waterway designs.
This study was able to quantitatively and qualitatively assess the earthquake impacts and then present a suite of potential maintenance options to mitigate those impacts.
The paper will draw specific examples from recent projects such as New York’s Rebuild by Design Competition, the 100 Resilient Cities Programme, The Copenhagen Cloudburst Management plan and New Orlean’s response to Hurricane Katrina as well identify how decentralized approaches to stormwater management including smaller scale catchment solutions (such as programmes of Water Sensitive Urban Design, Natural Flood Management) can yield multiple benefits for creating places where people want to live and work in harmony with nature.
This paper explores the benefits of a Modelling Project Office approach and how it differs to the traditional approach in terms of procurement, scope, collaboration, time and cost. It provides insights into how a collaborative approach between consultants and clients achieves better outcomes and cost savings for both parties and the local industry’s technical capabilities. It also provides discussions on the lessons learnt through the process.
The quality, fate and environmental implications of the stormwater discharges from the Northport Marsden Point deep-water port, located at the entrance to Whangarei Harbour are discussed. Northport is New Zealand’s newest port, opening in 2002.
To assist with planning of stormwater improvements to address water quality issues, an event-based contaminant load model has been developed that predicts the contributions from individual surfaces of TSS, copper and zinc based on rainfall characteristics such as rainfall intensity, antecedent dry period, storm duration, and rainfall pH.
