Introduction

With the rapid advancement of urbanization, urban water environments are facing unprecedented challenges (Chen et al. 2015). The continuous expansion of impervious surfaces has disrupted the natural water cycle, resulting in rapid stormwater runoff, increased frequency of urban flooding, and reduced groundwater recharge. At the same time, worsening water pollution and the intensifying urban heat island effect further highlight the limitations of traditional urban planning and design in adapting to hydrological systems.

引言

随着城市化的快速推进，城市水环境正面临前所未有的挑战 (Chen et al. 2015)。城市地表不透水面的持续扩张削弱了自然雨水循环，导致降雨径流迅速汇集，增加了内涝发生的频率，也降低了雨水对地下水的补给能力。同时，水体污染以及城市热岛效应的加剧，进一步暴露出传统城市规划对水文系统适应性的不足。在气候变化背景下，极端降雨、干旱等事件的发生频率和强度不断上升，这些现象正严峻考验着城市对水资源的调蓄、排涝、净化和生态恢复等能力。

在这个背景下，水敏感城市设计（Water Sensitive Urban Design, WSUD）作为一种新型城市发展模式被广泛关注。与“低影响开发”（Low Impact Development, LID）理念相似，水敏感城市设计强调模拟自然水循环过程，并提升城市应对水资源相关挑战的韧性。其核心目标在于将水资源视为城市系统中不可或缺的组成部分，通过系统性地管理水的收集、输送、处理与储存过程，实现其生态功能与社会功能的有机融合（Wong 2006）。

Data has become one of the most valuable resources of the 21st century. Indeed, data can be considered the most important input when it comes to make informed decisions. The recent global pandemic crisis highlighted the vital role of data for reporting accurate case numbers and outbreaks, identifying the most vulnerable demographics, and understanding the most effective vaccines, to mention few. Data also plays a key role when it comes to sustainability.

Locate21

Each year, the Locate conference attracts national and international delegates from within and outside the spatial & surveying industry. As Australia’s premier spatial & surveying conference, Locate provides guests with a unique opportunity to learn about the latest trends and applications in geospatial technologies and encourages them to harness the power of location like never before.

Virtually and in person, we will share how geospatial and location technologies and practices are being used, highlighting the fundamental role they play in enabling our digital economy

73rd IEC Meeting and 24th ICID International Congress on Irrigation and Drainage 2022

About the Congress

ICID has been organizing its flagship triennial event International Congress on Irrigation and Drainage since 1951. The 1st ICID Congress was held in 1951 at Delhi and so far ICID has held 23 Triennial Congresses.

Stakeholder

UN Environment

The United Nations Environment Programme (UN Environment) is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment. Our mission is to provide leadership and encourage partnership in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations.

GEO AquaWatch

AquaWatch is an Initiative within the Group on Earth Observations (GEO) that aims to develop and build the global capacity and utility of Earth Observation-derived water quality data, products and information to support water resources management and decision making.

Goal

The goal of the AquaWatch Initiative is to develop and build the global capacity and utility of Earth Observation-derived water quality data, products and information to support effective monitoring, management and decision making.

Objectives

The objectives to achieve this goal are:

University of Natural Resources and Life Sciences Vienna

Founded in 1872, the Universität für Bodenkultur Wien / University of Natural Resources and Life Sciences, Vienna, also known by its acronym "BOKU" is an education and research institution for renewable resources in Vienna, Austria. Today, BOKU comprises of 15 departments located at two sites in Vienna and one in Lower Austria, as well as several external research and teaching facilities in Austria. There are currently approximately 11000 students enrolled at BOKU in study courses at the bachelor, master, and doctoral levels.

UK Centre for Ecology and Hydrology

The UK Centre for Ecology & Hydrology (UKCEH) is a world-leading independent research institute focused on delivering integrated environmental science to address some of the most pressing challenges facing society and the planet. With over 50 years of expertise, UKCEH operates at the interface of ecology, hydrology, atmospheric science, and data science, providing evidence and tools to support sustainable environmental management.

University of Surrey

The University of Surrey is a leading research and higher education institution in the United Kingdom, known for its strengths in space technology and water research, among other fields.

Centre for Water and Landscape Dynamics, Australian National University

The ANU Centre for Water and Landscape Dynamics (WALD) is a world leader in observation technology for real time environmental information. WALD develops new methods to measure, monitor and forecast climate, water availability and landscape conditions. Our solutions frequently combine Big Data from satellite observation and sensor networks, with field research, biophysical modelling and machine learning.

FastFlood

FastFlood.org tool is an innovative flood simulation tool developed and maintained by Dr. Bastian van den Bout. FastFlood enables fast and efficient flood scenario calculations. Originally developed in 2021, the model has undergone continuous improvements and now offers over 97% accuracy, while being up to 1500 times faster than traditional flood modelling methods. This speed makes it an ideal solution for quick risk assessments and initial analyses. The model is available as a web-based application and free to use.
