The paradigmatic shift from traditional flood defense toward integrated flood risk management has widened the sectors and policies affected and has spurred a growing interest of scholars to understand cross-sectoral flood policy integration. In this paper we argue that the cross-sectoral goal relationship—ranging from complementary to conflictual policy goals—is a useful conceptual framework to understand (1) the policy integration challenge at hands and (2) in particular the unfolding policy integration from a processual perspective. For our empirical analysis we identify three policy subsystems that are highly important for sectoral interplay in flood risk management: agriculture, hydropower generation, and spatial planning. Using Austria as a case study we illustrate the goal relationships and sectoral policy integration challenges in each of these fields of interaction. Based on 45 expert interviews in the selected policy sectors we provide useful insights into the current processes of flood policy integration. The empirical findings from our case studies show that sectoral goal relationships and the nature of the policy integration challenge drive flood policy integration. More pronounced land use conflicts are more strongly reflected in different actor interests, policy frames, policy goals, and the choice of policy instruments. Sectoral goal relationships are an important factor to explain the unfolding policy integration process. Complementary policy goals result in rather informal, harmonious integrative negotiations on strengthening synergies by using soft policy instruments. On the contrary, conflictual policy goals lead to more formal negotiations among the affected sectors relying on hard, regulative instruments.

从传统防洪到综合洪水风险管理的范式转变扩大了受影响的部门和政策，并激发了学者们对理解跨部门洪水政策整合的兴趣。在本文中，我们认为，跨部门目标关系（从互补到冲突的政策目标）是一个有用的概念框架，可以理解（1）当前的政策整合挑战，（2）特别是从过程性的角度展开的政策整合。看法。在我们的实证分析中，我们确定了对于洪水风险管理部门相互作用非常重要的三个政策子系统：农业、水力发电和空间规划。我们以奥地利为案例研究，说明了每个互动领域的目标关系和部门政策整合挑战。基于所选政策部门的 45 名专家访谈，我们提供了有关当前洪水政策整合流程的有用见解。我们案例研究的实证结果表明，部门目标关系和政策整合挑战的性质推动了洪水政策整合。更明显的土地利用冲突更强烈地反映在不同主体的利益、政策框架、政策目标和政策工具的选择上。部门目标关系是解释正在展开的政策整合过程的重要因素。互补的政策目标导致就通过使用软政策工具加强协同作用进行相当非正式、和谐的综合谈判。相反，相互冲突的政策目标导致受影响部门之间依赖硬性监管工具进行更正式的谈判。
